RAYMOND BELLAMY, 0F MOORES HILL, INDIANA.

GAS-GENERATOR.

Specification of Letters Patent.

Patented Feb. 13, 1912.

ToaZZ whom itma-y concern: I

Be it known that l, RAYMOND BELLAMY, a citizen of the United States, residing at Moores Hill, in the county of Dearborn and State of Indiana, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification, ref erence being had to the accompanying drawings.

My invention relates'to new and useful improvements in gas generators and more particularly to a generator wherein the action of two chemicals combined generates the desired gas, and my object is to provide a device of this character which is of simple, durable and inexpensive construction for particularly laboratory use.

A further object of the in ventionresides in providing a receptacle for containing any desired liquid and a movable device in connection with the receptacle for containing a sblid, whereby when the solid is moved into the liquid, a chemical action will occur to generate the desired gases;

A still further object of the invention resides in providing an outletfor the from the receptacle, and a further object resides in providing means to prevent the outlet of the poisonous or obnoxious gases that may be generated.

l/Vith these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application, Figure 1 is a side elevation partly in section of the device set up for operation, and, Fig. 2 is a detail perspective view of the movable'device for containin the solidsubstance used in the generation of the gas' In carrying out my invcn-. tzion, I shall refor to the drawing in which similar rete'ren'ce characters designate corresponding parts throughout the several views and in which 1 indicates areceptacle such as a bottle or the like, preferably formed of glass, and of any desired size and shape, said bottle like receptacle having snugly fitting within the neck thereof, a rubber stopper or closure 2. This bottle receptacle is adapted to eontain an acid'or other liquid, such as would have a chemical effect upon certain matter,

and said stopper or closure 2 is provided with a pair of openings 3 extending verticallythcrethrough, one of said openings" having extending therethrough, a rod 4, the lower end of which is secured in any desired manner to a foraminous bowl'or cup-shaped 'Il'lLIIlbOI 5.

When the stopper '2 has been properly. positionedin the neck of the bottle 1, the walls of the opening through which the rod 4: extends, will grip tightly around said rod and retain the same in any adjusted position, but it will be appreciated that said rod may be raised or lowered to correspondingly raise :or lower the bowl5 with respect to the liquid 1 2, and it willbe appreciated that when the rod is lowered so as to allow the contents of the bowl-shaped member to be commingled with the liquid in the bottle, the gas will be generated and allowed to flow through said tube 6, and it, will also be understood that When it is desired to stop the generation of gas, the rod 4 may be raised to raise the discontinue the generation of gas. This sleeve member 7 may be provided with a rubber lining or bushing 8, if desired, so as r to fit snugly about the lower end of said tube to prevent any possible escape of gas, and from this consti'uction, it will be seen that both the generation and the flow of gas may be entirely cut off through the one vertical IIIOVOHICIlll of the rod 4.

FI'UmtlIO foregoing, itwill be seen that. I have provided an improved gas generating device which is-partieularly adapted for use in laboratories wherein a. solid is adapted to be lowered into a liquid, the chemical ac- I Y tion et which results in'.: the generation of gas. It will further be seen that by providing a toraminous bowl-shaped member, a solid may be readily carried therein, and when raised above the liquid, will allow any of the matter which is being dissolved, to drop therefrom into the liquid and at the same time, allow the remaining portion of the solid to be saved for' use at a further time. Furthermore, it will be seen that by providing a rubber stopper er closure, as described,

and movably mounting the rod which carries cheaply manufactured, and one which is very effective in operation.

alt

What I claim is 1. A device of the class described, comprising a receptacle, a removable closure therefor, said closure being provided with a. restricted outlet, a foraminous bowhshaped member disposed within said receptacle,

means to raise and lower the same, and.

means on said bowl-shaped member for clos ing the restricted outlet when the same is raised.

2. A device of theclass described, comprising a receptacle, a closure therefor, a tube mounted in said closure having the lower end thereof disposed a short distance ,within said receptacle,- a rod slidably mounted in said closure, a bowl-shaped member mounted on thelower end-of sald rod, and a sleeve member mounted within said bowlshaped member and adapted-to receive the lower end of said tube to close the same when said rod is raised.

In testimony wheredf I hereunto atiix my signature in the presence of two witnesses. RAYMOND BELLAMY. Witnesses J 01m F. SPENCER, GEORGE F. HYATT.
